Always be charging. That's what we do at CES. But there isn't always an outlet around, which is why Hyper's Pico charger is so awesome—it juices up three smartphones at the same time.

The 3000 mAh pack goes on sale in March through HyperShop.com for $70. It comes with retractable lightning and microUSB cables, along with an extra USB port. The max output is 15W, meaning you can gas up three phones or one phone and one tablet at a time. To charge the battery itself, plug an additional built-in USB into an adapter or directly into your computer, and you'll be back at full power in 2-3 hours. Pico's really small and really light so you'd hardly notice it in your bag, unless of course your phone was on its last leg.
